User familiarization with a novel route for reducing cognitive load associated with navigation

ABSTRACT

User behavior data and/or driver questionnaire data is received. Navigation information comprising point of interest data, entity of interest data, and/or roadway data is received. The navigation information is analyzed based on the user behavior data and/or driver questionnaire data to identify a navigation scenario that is expected to cause a user to have an increased cognitive load when navigating the navigation scenario. Scenario information for the navigation scenario is generated. The scenario information comprises scenario identifying information configured for identifying portions of a route that match the navigation scenario and/or information for generating familiarization information for a portion of a route matching the navigation scenario. The scenario information is used to identify a high cognitive load portion of a route by matching a portion of the route to the navigation scenario based on the scenario identifying information and/or generate familiarization information for the high cognitive load portion.

TECHNOLOGICAL FIELD

An example embodiment relates generally to reducing the cognitive loadof a user navigating a route. An example embodiment relates generally togenerating and providing optimum familiarization content to a user.

BACKGROUND

Navigating an unfamiliar route is often stressful. For example, if anintersection is an all-way stop intersection, but is not clearly markedas such, a user that is unfamiliar with the intersection may findnavigating through the intersection to be stressful. For example, thecognitive load on an individual (e.g., a human operator/driver of anautomobile or other vehicle) when navigating an unfamiliar route may bequite high compared to when navigating a familiar route. The demand ofcognitive resources for the primary task (e.g., operating/driving anautomobile or other vehicle) may be compromised by the allocation ofmore cognitive resources for navigating the unfamiliar route. Therefore,a user's unfamiliarity with a route may cause the user stress whennavigating the unfamiliar route and may negatively affect the user'sability to efficiently navigate the unfamiliar route.

BRIEF SUMMARY OF SOME EXAMPLE EMBODIMENTS

Various embodiments provide methods, systems, apparatuses, and computerprogram products for generating and providing familiarization content toa user navigating a route. For example, familiarization content may beprovided to a user navigating an unfamiliar and/or novel route. Variousembodiments provide methods, systems, apparatuses, and computer programproducts that generate and/or make use of entities of interest (EOIs)based on static and/or dynamic (e.g., time dependent) information/dataregarding a related and/or linked set of two or more points of interest(POIs). Various embodiments provide a human cognitive navigation modelthat may be used to identify portions of a navigation route that maycorrespond to an increased cognitive load for a human operator/drivernavigating the navigation route. For example, in an example embodiment,if a navigation system determines that a user has requested routeinformation/data for navigating an unfamiliar and/or novel route, anavigation engine may provide route information/data to an extractionengine that identifies high cognitive load portions of the route (e.g.,portions of the route that are expected to cause a user to have anincreased cognitive load while the user navigates the portion of theroute) based on a cognitive navigation model configured to model humancognitive processing of navigation processes. The cognitive navigationmodel may also receive configuration information/data such asinformation/data regarding the user (e.g., operating/driving experiencelevel, number of years operating/driving, user preferences, and/or thelike) and POI and/or EOI information/data for one or more POIs and/orEOIs located along the route. In an example embodiment, the cognitivenavigation model provides scenario information/data and/or scenariotemplates for use in identifying and/or determining portions of theroute that are likely to cause the user stress and/or are likely toincrease the user's cognitive load while navigating those portions ofthe route. The extraction engine may then generates and/or extractsfamiliarization information/data comprising familiarization contentregarding the identified and/or determined portions of the route. In anexample embodiment, the familiarization information/data correspondingto a high cognitive load portion is generated and/or extracted from theroute information/data based at least in part on the scenarioinformation/data and/or scenario template used to identify the highcognitive load portion. A vehicle apparatus onboard the vehicle beingoperated and/or driven by the user may then provide the familiarizationcontent to the user at appropriate points and/or times as the usernavigates the route in an efficient way.

In various embodiments, an EOI is an entity generated by linking two ormore POIs. In various embodiments, the linking between the two or morePOIs may be dynamic and/or time dependent. For example, an EOI may begenerated by linking a school, an ice cream shop near the school, and across walk between the school and the ice cream shop. The POIinformation/data corresponding to the school may indicate the time theschool day begins and/or ends (e.g., 8 am to 3 pm) and may also indicatedays on which the school is open or is not open (weekends, holidays,breaks, and/or the like). The POI information/data corresponding to theice cream shop may indicate the hours that the ice cream shop is open(e.g., that the ice cream shop is open from 2 pm to 8 pm). In an exampleembodiment, the EOI information/data may indicate that the EOI is onlyrelevant between 3 pm and 8 pm on days that the school is open. In anexample embodiment, the EOI information/data may further indicate thecurrent status of a walk signal located at the cross walk. For example,the EOI information/data may comprise (near) real-time information/datacorresponding to the status of a walk signal at the cross walk shortlybefore the user arrives at the cross walk. In various embodiments, EOIsmay be generated using an EOI model and/or other data extraction modelthat takes into account POI information/data (static and/or dynamic),map information/data (e.g., via a geographic database, one more maplayers, and/or the like), operating/driving effort information/data,weather information/data, current and/or historical trafficinformation/data, (near) real-time traffic system information/data,and/or the like. In various embodiments, two or more POIs may be linkedthrough a logical relationship and may be grouped together to form anEOI based on logical rules.

In an example embodiment, the cognitive navigation model istrained using navigation information/data, user behaviorinformation/data, and/or feedback directly from one or more users (e.g.,a user questionnaire). In an example embodiment, the cognitivenavigation model is trained using machine learning with support from amachine learning engine.

II. Example Operation

Example embodiments provide methods, apparatus, systems, computerprogram products, and/or the like for providing a user (e.g., anoperator/driver of a vehicle 5) with familiarization information/datafor portions of an unfamiliar and/or novel route that are associatedwith increased levels of cognitive load (e.g., high cognitive loadportions of the route). In an example embodiment, familiarizationinformation/data comprises familiarization content. The familiarizationcontent comprises information/data configured to be provided visually,audibly, and/or haptically to a user as the user navigates an unfamiliarand/or novel route and is configured to familiarize a user with thecorresponding high cognitive load portion of the route such that theuser's cognitive load while navigating the corresponding portion of theroute is decreased compared to if the familiarization content was notprovided to the user. In various embodiments, an unfamiliar and/or novelroute is a route that, according to a user profile corresponding to theuser, at least a portion of the route has not been previously navigatedby the user; when a new scenario (e.g., construction, different time ofday, a different day of the week than when the user usually navigatesand/or has previously navigated the route, different weather conditionsthan when the user has previously navigated the route, and/or the like);a route that the user has navigated only a few times (e.g., a number oftimes that satisfies a novelty threshold requirement); and/or route thatuser preferences stored in association with a user profile correspondingto the user indicate that the route should be considered unfamiliarand/or novel.

Cognitive load refers to the effort being used in the working memory ofa user. For example, when a user experiences an increased cognitiveload, the user is having to put greater effort into the use of workingmemory. Working memory is a human cognitive system with a limitedcapacity that is responsible for temporarily holding informationavailable for processing by the human brain. A heavy cognitive loadtypically creates error or some kind of interference in the task at hand(e.g., operating/driving a vehicle 5). Thus, various embodiments of thepresent invention provide familiarization content to a user (e.g., anoperator/driver of a vehicle 5) as the user navigates an unfamiliarand/or novel route so as to reduce the user's overall cognitive loadsuch to enable the user to maximize the amount of processing that may befocused on the task at hand (e.g., operating/driving the vehicle 5). Forexample, the familiarization content for an example high cognitive loadportion may comprise the text “take next right and the immediate leftafter 200 meters, which is followed by an immediate signal,” rather thanmerely instructing the user to “take the next right and then take thefirst left.” In another example, the familiarization content for anexample high cognitive load portion may comprise the text “usecaution—entering area with heavy pedestrian traffic including children.”

In various embodiments, EOIs may be determined and/or generated for usein identifying portions of a route that are associated with increasedcognitive load. For example, an EOI may be determined and/or generatedby identifying a link between two or more POIs. In an example, the linkmay be a dynamic link. As used herein, a dynamic link is a link betweentwo or more POIs that is determined and/or identified based on one ormore dynamic elements of at least one of the two or more POIs. As usedherein, a dynamic element is an element or field (e.g., and/or set ofassociated/linked fields) of an instance of POI (and/or EOI)information/data that is time dependent. In various embodiments, thetime dependence may be dependent on time of day, day of the week,calendar date, month, year, season, time of year, whether the day is aholiday or not, and/or other time dependent characteristic.

In various embodiments, high cognitive load portions of a route aredetermined and/or identified based on a user profile corresponding tothe user, a classification associated with the user (e.g., aclassification and/or class identifier stored in the user profile),and/or the like. In an example embodiment, determined and/or identifiedhigh cognitive load portions of a route are universal among varioususers (e.g., not user dependent). In various embodiments, the highcognitive load portions of a route are determined and/or identifiedbased on a human cognitive navigation model. In an example embodiment, ahuman cognitive navigation model is human cognitive model trained (e.g.,via machine learning) for modeling human cognitive patterns that relateto navigation.

Providing Familiarization Information/Data

In various embodiments, familiarization information/data comprisesfamiliarization content that is configured to be provided to a usernavigating an unfamiliar and/or novel route to reduce the user'scognitive load while navigating high cognitive load portions of theroute. As used herein a high cognitive load portion of a route is aportion of a route that is associated with increased cognitive load fora user navigating the route (e.g., operating/driving a vehicle along theroute). In various embodiments, an instance of familiarizationinformation/data corresponds to a high cognitive load portion andcomprises a trigger point and text, graphics, a template for generatingtext and/or graphics, and/or the like to be provided to a user (e.g.,via an IUI provided via the user interface 28 of a vehicle apparatus20), computer executable instructions for generating and/or providingtext, graphics and/or the like to be provided to a user, and/or thelike. In an example embodiment, an instance of familiarizationinformation/data comprises (a) a location of a high cognitive loadportion (e.g., identifying the location at which a user will enter ahigh cognitive load portion along the route, designating a section ofthe route as a high cognitive load portion, and/or the like), (b) atrigger point (e.g., a particular location along the route at which thefamiliarization content should be provided to the user and/or aparticular amount of time before the user is expected to reach the highcognitive load portion at which the warning and/or alert should beprovided to the user), (c) the familiarization content to be provided tothe user via the user interface 28 (e.g., text to be audibly provided toa user, text and/or graphics to be visually provided to the user, and/orthe like), and/or the like. In an example embodiment, thefamiliarization information/data further comprises one or more settingsmodifications. In an example embodiment, a settings modification may bean instruction (e.g., computer-executable instruction) that causes oneor more settings of the vehicle apparatus 20 to be updated. For example,one or more settings of a navigation application operating on thevehicle apparatus 20 (e.g., the application causing the IUI to the uservia the user interface 28) may be updated and/or modified. In an exampleembodiment, the navigation engine 300 and/or navigation applicationoperating on the vehicle apparatus 20 may be configured to manage,update, modify, and/or the like one or more operating parameters of thevehicle 5 (e.g., braking responsiveness, handling responsiveness,daytime running lights and/or headlight operation, driving mode, and/orthe like) based on the settings modifications.

FIG. 3 illustrates a portion of a road network 850 comprising a route800. In an example embodiment, a route 800 corresponds to a particulartrip, wherein a particular trip is defined by an origin location, adestination location, and a time (e.g., a date/time of arrival, adate/time of departure, a date/time when the user is expected to belocated at a particular position along a route from the origin locationto the destination location, and/or the like). The route 800 extendsfrom an origin location 802 to a destination location 804 and comprisestwo high cognitive load portions 806 and 812. High cognitive loadportion 806 corresponds to EOI 808 and high cognitive load portion 812corresponds to a portion of the route with high driving difficulty(e.g., where A Street dog-legs across Second Avenue). In an exampleembodiment, familiarization content corresponding to high cognitive loadportion 806 is visually, audibly, and/or haptically provided to the user(via the user interface 28 of the vehicle apparatus 20) when the user(e.g., as determined by a location sensor 29 of the vehicle apparatus20) is located at and/or has passed through trigger point 810. Forexample, when the user (e.g., as determined by a location sensor 29 ofthe vehicle apparatus 20) is located at and/or has passed throughtrigger point 810, the vehicle apparatus 20 may use a speaker of theuser interface 28 (and/or of the vehicle 5) to audibly provide the userwith a warning and/or alert regarding approaching the EOI 808 andindicating actions a user should take (be alert, be aware that a largenumber of pedestrians may be crossing the street, be aware that childrenmay be walking on the sidewalk, and/or the like). As should beunderstood, the warning and/or alert is tailored to the correspondinghigh cognitive load portion and/or extracted from EOI and/or routeinformation/data (e.g., map information/data corresponding to the links,nodes, intersections, road geometry, road topology, POIs, EOIs and/orthe like along the route) for the corresponding high cognitive loadportion. The trigger point corresponding to high cognitive load portion812 is designated as trigger point 814. In various embodiments, atrigger point may be a particular location along a route (e.g., 100meters, 500 meters, 1000 meters, 1500 meters, 2000 meters and/or thelike before the corresponding high cognitive load portion) or aparticular time period ahead of when a user is expected to reach thecorresponding high cognitive load portion (e.g., 30 seconds, one minute,ninety seconds, two minutes, five minutes, and/or the like before theuser is expected to reach the high cognitive load portion). In anexample embodiment, the particular location or the particular timeperiod may depend on a classification (EOI, road geometry/topology,and/or the like) of the high cognitive load portion 812, the visibilityof the high cognitive load portion as the user approaches the highcognitive load portion, and/or the like.

This time may beused to identify relevant dynamic EOI and/or POI information/data forthe route of a particular trip.

The extraction engine 100 generates and/or extracts familiarizationinformation/data from the route information/data for the high cognitiveload portions of the route. In an example embodiment, familiarizationinformation/data comprises (a) a location of a high cognitive loadportion (e.g., identifying the location at which a user will enter ahigh cognitive load portion along the route, designating a section ofthe route as a high cognitive load portion, and/or the like), (b) atrigger point (e.g., a particular location along the route at which thewarning and/or alert should be provided to the user and/or a particularamount of time before the user is expected to reach the high cognitiveload portion at which the warning and/or alert should be provided to theuser), (c) the familiarization content to be provided to the user viathe user interface 28 (e.g., text to be audibly provided to a user, textand/or graphics to be visually provided to the user, and/or the like),and/or the like. In an example embodiment, the familiarizationinformation/data further comprises one or more settings modifications.In an example embodiment, the extraction engine 100 is configured toprovide the familiarization information/data 150 such that thefamiliarization content may be provided to the user. In an exampleembodiment, extraction engine 100 provides the familiarizationinformation/data to an application operating on the vehicle apparatus20. In an example embodiment, the extraction engine 100 provides one ormore settings modifications to the navigation engine 300 based on theextracted and/or generated familiarization information/data and/or routeinformation/data corresponding to the high cognitive load portions ofthe route. In an example embodiment, the navigation engine 300 updatesthe settings used to provide information/data to a user (e.g., via theuser interface 28) based on the settings modifications. In an exampleembodiment, the navigation engine 300 may be configured to manage,update, modify, and/or the like one or more operating parameters of thevehicle 5 (e.g., braking responsiveness, handling responsiveness,daytime running lights and/or headlight operation, driving mode, and/orthe like) based on the settings modifications.

In various embodiments, an extraction engine 100 comprises an EOIcreation engine 110, a content generation engine 120, an identificationengine 130, and/or the like. For example, the EOI creation engine may beconfigured for generating and/or creating one or more EOIs based on POIinformation/data for one or more POIs. EOI creation is describedelsewhere herein in detail.

In various embodiments, the identification engine 130 uses scenarioinformation/data and/or scenario templates provided by one or more highcognitive load models 200 (e.g., a cognitive navigation model 205) toanalyze the route information/data (including EOI information/datacorresponding to EOIs located along the route) for the route todetermine and/or identify high cognitive load portions of the route. Forexample, in an example embodiment, the scenario information/data and/orscenario templates may provide templates and/or threshold requirementsfor various high load navigation scenarios (e.g., navigation scenariosthat may increase cognitive load for a user navigating the navigationscenario). In an example embodiment, the identification engine 130 isconfigured to review, analyze, and/or the like EOI information/data, POIinformation/data, roadway information/data (e.g., geometry and/ortopology information/data of one or more roads corresponding to a routeto determine and/or identify high cognitive load portions of the route.In an example embodiment, an identification engine 130 may determine ifa property of a road segment, link, and/or the like (e.g., based on theroad geometry and/or topology information/data) satisfies one or morethreshold requirements of an instance of scenario information/dataand/or scenario template. For example, in an example embodiment, if thecurvature of a section of a road segment satisfies a first curvaturethreshold requirement, the section of the road segment is identified asa high cognitive load portion; if there is a driveway or road and/orintersection that is located at a point along a section of a roadsegment that has a curvature that satisfies a second curvature thresholdrequirement, the section of the road segment is identified as a highcognitive load portion; if a section of a road segment has a grade orslope that satisfies a first grade threshold requirement, the section ofthe road segment is identified as a high cognitive load portion; if asection of the road segment has a grade or slope that satisfies a secondgrade threshold requirement and a curvature that satisfies a thirdcurvature threshold requirement, the section of the road segment isidentified as a high cognitive load portion; and/or the like. In variousembodiments, the identification engine 130 may compare one or moretemplates to the route information/data to determine if a template fitsany portion of the route information/data and/or if any portion of theroute information/data satisfies a threshold requirement to determineand/or identify high cognitive load portions of the route.

In various embodiments, the content generation engine 120 is configuredto create and/or generate familiarization information/data for thedetermined and/or identified high cognitive load portions of the route.For example, the content generation engine 120 may generate thefamiliarization content, determine and/or identify the trigger point atwhich the familiarization content should be provided to the user,determine and/or generate setting modifications, and/or the like.

FIG. 6 provides a flowchart of example processes, operations,procedures, and/or the like of a network apparatus 10 for providing auser with familiarization content, according to an example embodiment.Starting at block 502, new route information/data is received. Forexample, the network apparatus 10 receives new route information/data.For example, the network apparatus 10 comprises means, such as processor12, memory 14, communications interface 16, and/or the like forreceiving new route information/data. In an example embodiment, the newroute information/data comprises complete route information/data for aroute of a particular trip. In an example embodiment, the new routeinformation/data comprises information/data defining a particular trip(e.g., an origin location, a destination location, and a time) and thenavigation engine 300 generates the route information/data for the routebased on the new route information/data.

In an example embodiment, the new route information/data is provided(e.g., transmitted) by the vehicle apparatus 20. For example, in anexample embodiment, a vehicle apparatus 20 may operate a navigationapplication configured to provide a user with an IUI via the userinterface 28 of the vehicle apparatus 20. The IUI may be configured toreceive (e.g., via user interaction with the user interface 28 and/orthe like) information/data defining a particular trip. For example, auser may provide input identifying a destination location, an originlocation, and a time. In an example embodiment, the user may provideinput via the user interface 28 identifying a destination location andthe navigation application may assume that the origin location is thecurrent location of the user (e.g., as determined by the location sensor29 of the vehicle apparatus 20) and the time is depart at the currenttime unless the user provides input (e.g., via the user interface 28)indicating a different origin location and/or time. In an exampleembodiment, a user may provide input comprising a destination address(e.g., a street address), a destination geolocation (e.g., longitude andlatitude), a name of a POI located at the destination location,selecting a position on a map, and/or the like to provide inputindicating the destination location. Similarly, a user may provide inputcomprising an origin address, an origin geolocation (e.g., longitude andlatitude), a name of a POI located at the origin location, selecting aposition on a map, and/or the like to provide input indicating theorigin location. Upon receipt of the new route information/data (e.g.,via the user interface 28), the vehicle apparatus 20 may provide the newroute information/data to the network apparatus 10. In an exampleembodiment, the vehicle apparatus 20 may determine a route based on thenew route information/data and include route information/datacorresponding to the determined route as part of the new routeinformation/data. In an example embodiment, the vehicle apparatus 20 mayprovide the new route information/data to the network apparatus 10 suchthat the network apparatus 10 may determine a route based on the newroute information/data.

After the receiving the new route information/data, the networkapparatus 10 may determine a route based on the new routeinformation/data, if the new route information/data does not indicate aroute. For example, the navigation engine 300 may determine a routebased on the new route information/data. Then, at block 504, it may bedetermined if the route is an unfamiliar and/or novel route for theuser. For example, the network apparatus 10 (e.g., the extraction engine100 operating on the network apparatus 10) may determine if the route isan unfamiliar and/or novel route for the user. For example, the networkapparatus 10 may comprise means, such as the processor 12, memory 14,and/or the like, for determining if the route is an unfamiliar and/ornovel route for the user. In various embodiments, an unfamiliar and/ornovel route is a route that, according to a user profile correspondingto the user, at least a portion of the route has not been previouslytraversed by the user; when a new scenario (e.g., construction,different time of day, a different day of the week than when the userusually traverses and/or has previously traversed the route, differentweather conditions than when the user has previously traversed theroute, and/or the like); a route that the user has traversed only a fewtimes (e.g., a number of times that satisfies a novelty thresholdrequirement); and/or route that, based on user preferences stored inassociation with a user profile corresponding to the user indicate thatthe route should be considered unfamiliar and/or novel. In an exampleembodiment, if it is determined that the route is not unfamiliar and/ornovel for the user, the process may end (e.g., familiarizationinformation/data may not be determined and provided to the user). In anexample embodiment, if it is determined that the route is unfamiliarand/or novel for the user the process continues to block 506.

At block 506, the extraction engine 100 operating on the networkapparatus 10 receives information/data from the navigation engine 300(which may also be operating on the network apparatus 10). For example,the network apparatus 10 may comprise means, such as processor 12,memory 14, and/or the like, for passing information/data from thenavigation engine 300 to the extraction engine 100. For example, thenavigation engine 300 may pass route information/data (including POIand/or EOI information/data for the route such as static and/or dynamicelements of the POI information/data), weather information/data, drivingeffort information/data, traffic information/data, and/or otherinformation/data corresponding to the route such that theinformation/data is received by the extraction engine 100.

At block 508, one or more EOIs may be generated. For example, based onthe POI information/data for the route the EOI creation engine 110(operating on the network apparatus 10) may generate one or more EOIscorresponding to the route. For example, the EOI creation engine 110operating on the network apparatus 10 may generate one or more EOIscorresponding to the route. In an example embodiment, the networkapparatus 10 comprises means, such as the processor 12, memory 14,and/or the like, for generating one or more EOIs corresponding to theroute. In an example embodiment, the EOI creation engine 110 maygenerate, maintain, and/or the like an EOI data store (e.g., an EOIdatabase) comprising EOI information/data for previously generated EOIs.The EOI creation engine 110 may update the EOI data store with any EOIinformation/data for the one or more generated EOIs corresponding to theroute. The EOI creation engine 110 may, prior to generating the one ormore EOIs, determine if there are any EOIs corresponding to the routestored in the EOI data store and access the corresponding EOIinformation/data from the EOI data store. For example, the EOI creationengine 110 may minimize the number of EOIs that need to be created for aroute by accessing previously generated EOIs stored in the EOI datastore.

At block 510, the extraction engine 100 receives information/data fromthe high cognitive load model 200. For example, the extraction engine100 (operating on the network apparatus 10) may pass a request forinformation/data to the high cognitive load model 200 (operating on thenetwork apparatus 10) and, responsive thereto, receive scenarioinformation/data and/or scenario templates from the high cognitive loadmodel 200. For example, the network apparatus 10 may comprise means,such as processor 12, memory 14, and/or the like, for passinginformation/data from the high cognitive load model 200 to theextraction engine 100. For example, the extraction engine 100 mayreceive driving characteristics information/data corresponding to how aindividual user and/or a generic user (possibly of a particular class ofusers) responds to various driving scenarios, information/data regardingnavigation scenarios that tend to lead to an increase cognitive load fora user, behavior aspects information/data regarding a individual userand/or a generic user (possibly of a particular classification of user)behavior (e.g., response to various types of familiarization contentwarnings, notifications, text, graphics, and/or alerts, and/or thelike), constraints, and/or other information/data from the highcognitive load model 200. For example, in an example embodiment, thehigh cognitive load model 200 (and/or a plurality of high cognitive loadmodels 200) may provide templates and/or threshold requirements forvarious scenarios that may increase cognitive load for a user. In anexample embodiment, the information/data provided by the high cognitiveload model 200 to the extraction engine 100 may be user specific. Forexample, the high cognitive load model 200 may be personalized based onuser behavior information/data stored in the user behavior database 260,a user profile, and/or the like. In an example embodiment, a user may beassociated with a class of users (e.g., new operators/drivers, elderlyoperators/drivers, aggressive operators/drivers, timidoperators/drivers, and/or the like) and the high cognitive load model200 may be personalized for a class of users. In an example embodiment,a class of users is a group of users that have at least one attribute incommon. For example, a classes of users may be generated by groupingusers by at least one of age, years driving, driving experience, drivingbehavior, user preferences, and/or the like. Thus, in variousembodiments, the information/data provided by the high cognitive loadmodel 200 to the extraction engine 100 may be personalized for the userand/or a class associated with the user.

At block 512, the high cognitive load portions are determined and/oridentified. For example, the identification engine 130 (operating on thenetwork apparatus 10) may identify and/or determine the high cognitiveload portions for the route based on the information/data received fromthe high cognitive load model 200 and the navigation information/datareceived from the navigation engine 300. In an example embodiment, thenavigation information/data received form the navigation engine 300comprises route information/data such as POI information/data, EOIinformation/data, and/or roadway information/data (e.g., from linkand/or node data records) corresponding to the route. For example, thenetwork apparatus 10 may comprise means, such as the processor 12,memory 14, and/or the like, for determining and/or identifying highcognitive load portions of a route. As noted above, the extractionengine 100 may further receive additional information/data (e.g., time,configuration information/data, and/or the like) and the determinationand/or identification of the high cognitive load portions may be furtherbased on the additional information/data. In various embodiments, theidentification engine 130 may compare one or more templates and/orthreshold requirements provided by the high cognitive load model 200 tothe route information/data provided by the navigation engine 300 todetermine if a template fits any portion of the route information/dataand/or if any portion of the route information/data satisfies athreshold requirement to determine and/or identify high cognitive loadportions of the route. For example, the identification engine 130 may beconfigured and/or programmed to determine portions of the route that arelikely to increase the cognitive load of a user navigating the routebased on the information/data provided by the high cognitive load model200 and the route information/data provided by the navigation engine300.

At block 514, familiarization information/data is extracted and/orgenerated. For example, the content generating engine 120 (operating onthe network apparatus 10) may extract and/or generated familiarizationinformation/data based on the configuration information/data (e.g., userpreferences for the user as stored in association with a user profilecorresponding to the user) and the route information/data correspondingto the identified and/or determined high cognitive load portions for theroute. For example, the network apparatus 10 may comprise means, such asprocessor 12, memory 14, and/or the like, for extracting and/orgenerating familiarization information/data. For example, theidentification engine 130 may pass information/data identifying the highcognitive load portions for the route to the content generating engine120. The content generating engine 120 may then use configurationinformation/data, such as user preferences for the user, to generateand/or extract familiarization information/data from the routeinformation/data for the route corresponding to the high cognitive loadportions of the route. For example, the content generation engine 120may generate the familiarization content, determine and/or identify thetrigger point at which the familiarization content should be provided tothe user, determine and/or generate setting modifications, and/or thelike based on the configuration information/data and the routeinformation/data.

In an example embodiment, the content extraction engine 120 may furthergenerate and/or extract one or more settings modifications, at block516. For example, the one or more settings modifications may beconfigured for updating one or more settings of the navigation engine300 (e.g., a portion of the navigation engine 300 such as a navigationapplication operating on the vehicle apparatus 20 and providing the IUIto the user via the user interface 28). For example, the contentextraction engine 120 (operating on the network apparatus 10) maydetermine, generate, and/or extract one or more settings modificationsbased on the configuration information/data, route information/data,and/or the like. For example, the settings modifications may beconfigured to update settings of a navigation application operating onthe vehicle apparatus 20 (e.g., to provide the IUI to the user via theuser interface 28) to provide the user with information regarding anupcoming maneuver more times and/or earlier in the route than if theuser was familiar with the route. In various embodiments, the settingsmodifications may cause one or more modifications of the operatingparameters of the vehicle 5. In an example embodiment, the vehicleapparatus 20 may be configured to manage, update, modify, and/or thelike one or more operating parameters of the vehicle 5 (e.g., brakingresponsiveness, handling responsiveness, daytime running lights and/orheadlight operation, driving mode, and/or the like) based on thesettings modifications. In an example embodiments, the settingsmodifications are included in an instance of familiarizationinformation/data and/or alongside the familiarization information/data.

At block 518, the route information/data and the familiarizationinformation/data is provided to the vehicle apparatus 20. In an exampleembodiment, one or more settings modifications may be provided to thevehicle apparatus 20 alongside and/or as part of the routeinformation/data and/or the familiarization information/data. Forexample, the network apparatus 10 may transmit and/or provide the routeinformation/data and the familiarization information/data (and possiblysettings modifications). For example, the network apparatus 10 maycomprise means, such as processor 12, memory 14, communicationsinterface 16, and/or the like, for transmitting and/or providing theroute information/data and the familiarization information/data (andpossibly settings modifications). In an example embodiment in which thenew route information/data include route information/data for a route,the network apparatus 10 may only provide the familiarizationinformation/data (possibly including and/or accompanied by settingsmodifications). For example, the vehicle apparatus 20 may receive thefamiliarization information/data (possibly including and/or accompaniedby settings modifications) and may also receive route information/data.For example, the vehicle apparatus 20 may comprise means, such as theprocessor 22, memory 24, communications interface 26, and/or the like,for receiving the familiarization information/data (possibly includingand/or accompanied by settings modifications) and may also receive routeinformation/data.

In an example embodiment, upon receipt of settings modifications, thevehicle apparatus 20 may enact the settings modifications (e.g.,changing and/or updating one or more settings of the vehicle apparatus20, operating parameters of the vehicle 5, and/or the like). In anexample embodiment, one or more settings modifications correspond tohigh cognitive load portions of the route and those settingsmodifications may be implemented at the trigger point (and/or a separatesettings trigger point) corresponding to the corresponding highcognitive load portions and indicated by the corresponding instance offamiliarization information/data.

The user may then navigate the route in accordance with the routeinformation/data. For example, the IUI presented to the user via theuser interface 28 may provide the user with a map showing the route,turn-by-turn instructions for navigating the route, and/or the like. Theuser may then navigate the route based on the route information/dataprovided via the IUI. The vehicle apparatus 20 may cause the locationsensor 29 to track the location of the user as the user navigates theroute. When the user arrives at a trigger point indicated by an instanceof familiarization information/data, the familiarization content of theinstance of familiarization information/data is provided to the user viathe IUI provided via the user interface 28. For example, in an exampleembodiment, when a vehicle apparatus 20 determines that the user islocated at a position (e.g., a street address, a geolocation such aslatitude and longitude, a particular intersection and/or road segment,and/or the like) along the route and/or has passed through a positionalong the route indicated by the trigger point of an instance offamiliarization information/data, the processor 22 and the navigationapplication causes the user interface 28 to provide the familiarizationcontent to the user. For example, in an example embodiment, when thevehicle apparatus 20 estimates that the user will reach a high cognitiveload portion in a particular amount of time (as indicated by thecorresponding trigger point), the processor 22 and the navigationapplication causes the user interface 28 to provide the familiarizationcontent to the user.

As should be understood, various embodiments relate to aiding a humanoperator/driver of a vehicle reduce his or her cognitive load whiletraversing an unfamiliar and/or novel route. However, some embodimentsmay be adapted to provide familiarization information/data to a vehiclecontrol system of an autonomous driving system and/or ADAS. In anexample of one such embodiment, a cognitive model configured todetermine and/or identify portions of a route at which an autonomousdriving system and/or ADAS may be “overwhelmed” or overloaded inprocessing sensor data collected as the vehicle 5 traverses the route(e.g., urban canyons in which localization cannot depend on GNSS data,areas having a large number of features and/or a large amount ofnon-static objects within a camera field of view, areas having largenumbers of pedestrians, and/or the like) is used to identify the highcognitive load portions. Thus, while the present invention is generallydescribed herein as corresponding to providing familiarization contentto a human user (e.g., a human operator/driver of a vehicle 5), variousembodiments provide familiarization information/data to an autonomousdriving system and/or ADAS.

Generating EOIs

In various embodiments, POIs are described by a POI model. In variousembodiments, a POI model comprises POI information/data formatted inaccordance with a defined data model. In an example embodiment, a POImay be associated with a type and the corresponding POI model maycorrespond to a defined data model of the corresponding type. Forexample, a first data model may be defined for use with POIs that arerestaurants and a second, different data model may be defined for usewith POIs that are public parks. Some non-limiting types of POIs mayinclude restaurants, storefronts, businesses, public services offices,shipping/receiving locations, gas stations, public parks, cross walks,traffic signals, bus and/or other public transportation stops/stations,and/or the like, in an example embodiment. In various embodiments, thePOI model may be formatted such that familiarization contentcorresponding to the POI may be readily determined, generated, and/orextracted therefrom.

In various embodiments, the data model comprises one or more staticelements for static information/data corresponding to the POI, whereinstatic information/data is generally not time dependent. For example,the static information/data for a POI may comprise a street address ofthe POI; a geolocation of the POI; a description of the POI; one or moreconsumer reviews corresponding to the POI; size, color, and/or otherappearance aspects of the POI; and/or other information/data regardingthe POI that is generally not time dependent. The data model may furthercomprise one or more dynamic elements for dynamic information/datacorresponding to the POI. Dynamic information/data that is generallytime dependent. For example, the dynamic information/data for a POI maycomprise an indication of whether a business, school, publicbuilding/park, and/or the like corresponding to the POI is open orclosed; if a bus is arriving and/or located at a bus stop correspondingto a POI; if the POI is expected to be experience/causing a highpedestrian and/or vehicle traffic situation (e.g., a stadium is hostinga professional sports game, concert, conference, and/or the like and ishigher levels of pedestrian and/or vehicle traffic are expected in thevicinity of the stadium); a cross walk signal has been activated; and/orother time dependent information/data. For example, the dynamicinformation/data may change based on time of day, day of the week,month, calendar day, live (e.g., real-time or near real-time) trafficinformation/data, and/or the like. In various embodiments, static and/ordynamic information/data corresponding to a POI along a route may beused to determine and/or identify high cognitive load portions of theroute and/or to determine, generate, and/or extract familiarizationcontent corresponding to the high cognitive load portions along theroute.

In various embodiments, it may be determined that two or more POIs maybe linked such that the link between the two or more POIs affects theexperience of navigating a route in the vicinity of the linked POIs. Forexample, two or more POIs may be linked to generate an EOI. In variousembodiments, an EOI is described by EOI an EOI model. In variousembodiments, an EOI model comprises EOI information/data formatted inaccordance with a defined EOI data model. In an example embodiment, anEOI may be associated with a type and the corresponding EOI model maycorrespond to a defined data model of the corresponding type. Forexample, a first data model may be defined for use with EOIs thatcorrespond to increased pedestrian traffic and a second, different datamodel may be defined for use with EOIs that correspond to difficult roadtopologies. In an example embodiment, the POIs linked to generate an EOImay be located near one another. For example, the POIs may be locatedwithin a predefined distance of at least one other POI of the EOI. In anexample embodiment, the predefined distance may be based on a type ofthe EOI. For example, a type EOI corresponding to increased pedestriantraffic may have a smaller predefined distance than a type of EOIcorresponding to increased vehicle traffic, road topology, and/or thelike. In various embodiments, the EOI model may be formatted such thatfamiliarization content corresponding to the EOI may be readilydetermined, generated, and/or extracted therefrom.

In various embodiments, an EOI data model may comprise static anddynamic elements. For example, EOI information/data comprises generallytime independent static information/data and time dependent dynamicinformation/data. For example, the dynamic information/data may changebased on time of day, day of the week, month, calendar day, live (e.g.,real-time or near real-time) traffic information/data, and/or the like.In various embodiments, EOI information/data is generated and/ordetermined based on the POI information/data corresponding to the two ormore POIs linked to generate the EOI. In various embodiments, staticand/or dynamic information/data corresponding to an EOI along a routemay be used to determine and/or identify high cognitive load portions ofthe route and/or to determine, generate, and/or extract familiarizationcontent corresponding to the high cognitive load portions along theroute.

In an example embodiment, an EOI model may comprise a list of POIidentifiers identifying the two or more linked POIs (and/or thecorresponding POI models) corresponding to the EOI, an indication of therelationship between the two or more POIs corresponding to the EOI, timeinformation/data that, in various circumstances, should be consideredfor the two or more POIs corresponding to the EOI, and/or otherinformation/data corresponding to the EOI. For example, an EOI model maybe represented by the array {POIM1, . . . , POIMn, POIR, T, O}, whereinPOIM1, . . . , POIMn, are POI identifiers identifying the two or morePOI models corresponding to the POIs linked to generate the EOI, POIRdescribes the relationship between the linked POIs, T is the timeinformation/data, and O is other information/data corresponding to theEOI.

For example, an EOI may be generated that comprises the following POIs:an ice cream shop, a school, and a cross walk signal. In this example,the relationship between the linked POIs may be ice cream shop within xmeter radius of school with routing between school and ice cream shopincluding a cross walk corresponding to the cross walk signal. In anexample embodiment, the status of the cross walk signal may be takeninto account. In an example embodiment, the status of the cross walksignal may not be taken into account because a significant number of thepedestrians expected to cross the cross walk are children. The timeinformation/data may comprise the hours that the ice cream shop is open,the lunch break time at the school, the evening/afternoon closing timefor the school, and/or the like. The other information/data may compriseother information/data to be considered as necessary/relevant such as,for example, reduced visibility due to fog or other weather conditions,the present speed of the vehicle (e.g., may indicate to the vehicleapparatus 20 how assertively and/or the timing when the user should beprovided with the corresponding familiarization information/data),and/or the like.

Another example EOI may be defined by the set of POI models comprising astadium, the available/open parking lots and/or parking decks within afirst predefined distance of the stadium, bus stops and/or other publictransit stops and/or stations within a second predefined distance of thestadium, and any routing POIs (e.g., cross walks, cross walk signals,and/or the like) between the parking lots, parking decks, and/or busstops and/or other public transit stops and/or stations and the stadium.

FIG. 7 provides a block diagram of an EOI generation system 600 forgenerating, determining, identifying, and/or the like EOIs. In anexample embodiment, the EOI generation system 600 comprises and/orreceives information/data from navigation engine 300. For example, thenavigation engine 300 may provide static POI information/data, dynamicPOI information/data, weather information/data, driving effortinformation/data, and/or other information/data to the EOI modelcreation engine 610 and/or the EOI creation engine 110. In an exampleembodiment, if EOIs are being generated, extracted, and/or identifiedfor a particular route, the navigation engine 300 may provide routeinformation/data for the route. In an example embodiment, the EOIgeneration system 600 further comprises a navigation data interface 630configured to allow the EOI generation system 600 to interface withvarious sources of geographic information/data (e.g., a geographicdatabase, digital map, and/or the like).

In various embodiments, the EOI generation system 600 includes anexternal data extraction model 620. For example the external dataextraction model 620 may be the high cognitive load model 200 (e.g., acognitive navigation model 205), a fuel saving model, and/or other dataextraction model. The external data extraction model 620 may begenerated externally to the EOI generation system 600 and then used toinform the creation of EOI models. In an example embodiment, theexternal data extraction model 620 may comprise EOI data models that maybe used for generating EOI models and EOI generation system 600 may notinclude the EOI model generation engine 610. In various embodiments, theexternal data extraction model 620 provides data extractioninformation/data to the EOI model generation engine 610 and/or EOIgeneration engine 110. For example, the external data extraction model620 may indicate elements to include in the EOI data model such that EOImodels generated based on the EOI data model will be configured toprovide efficient and effective information/data for a desired purpose.For example, if the external data model 620 is a cognitive navigationmodel 205, the EOI data models may be configured to generate EOI modelsthat provide efficient and effective information/data for routedetermination and/or familiarization information/data extraction,determination, and/or generation.

In an example embodiment, the EOI model generation engine 610 isconfigured to receive data extraction information/data provided by theexternal data extraction model 620 and use the data extractioninformation/data to generate EOI models from the information/dataprovide by the navigation engine 300 and/or other geographicinformation/data. For example, in an example embodiment, the EOI modelgeneration engine 610, with the use of machine learning engine 650,learns to identify clusters of POIs that may be linked to form an EOI.For example, an EOI model generation engine 61 may be trained usingmachine learning as supported by the machine learning engine 650. In anexample embodiment, the EOI model generation engine 610 is configured todefine one or more EOI data models that may be used for generatingand/or describing EOIs based on information/data provided by thenavigation engine 300 and/or other geographic information/data. Forexample, the EOI model generation engine 610 may define one or more datamodels corresponding to different types of EOIs and/or differentscenarios that may cause POIs to be linked and/or have a relationshipwith one another. For example, one example EOI model may be configuredto provide a data model for EOIs comprising (a) a first POI that is aschool and/or other POI that children are known to frequent, (b) anattraction of interest to children (e.g., ice cream shop, candy store,soccer field, and/or the like) within a predefined radius of the firstPOI (e.g., a tenth of a mile, a quarter of a mile, half a mile, half akilometer, one kilometer, one and a half kilometers, and/or the like),and (c) any cross walks, cross walk signals, and/or other routing POIslocated along expected walking routes between the first POI and thesecond POI. In an example embodiment, the EOI model generation engine610 generates one or more EOI models to be used as templates foridentifying and/or determining EOIs from information/data provided bythe navigation engine 300 and/or other geographic information/data. Inan example embodiment, one or more dynamic elements of the data modelmay allow for the consideration of outdoor temperature and/or otherweather information/data (e.g., few children are likely to be walking tothe soccer field after school if it is raining outside or extremelycold/hot), time of day (e.g., it is unexpected that children will bewalking from the school to an ice cream shop at 9 am), day of the weekand/or calendar day (e.g., for determining if the school and/or otherPOIs are open or closed that day), and/or the like.

The EOI model generation engine 610 may be configured to provide the oneor more defined EOI data models to the EOI generation engine 110. Invarious embodiments, the EOI model generation engine 610 may furtherprovide the EOI generation engine 110 within information/data such asdriving characteristics (e.g., example characteristics ofoperators/drivers that should be warned, alerted, and/or notifiedregarding the EOI), behavioral aspects (e.g., information/data regardingvarious POIs that may be linked due to human behavior such as thelinking of a school to an ice cream shop or a parking lot to a nearbystadium), constraints (e.g., the predefined distances between POIs thatare available for linking into various types of EOIs), and/or otherinformation/data. The EOI generation engine 110 may then use the EOIdata models and other information/data provided by the EOI modelgeneration engine 610 to identify, determine, and/or generate EOIs basedon the information/data provided by the navigation engine 300 and/orother geographic information/data. For example, the EOI generatingengine 110 may be determine if there are any clusters of POIs along theroute that satisfy one or more conditions, match an EOI template, fit anEOI data model, and/or the like. If a cluster of POIs along the route(and/or in a geographic area being considered) are determined to satisfyone or more conditions, match an EOI template, fit an EOI data model,and/or the like, the cluster of POIs may be linked to generate an EOIand a corresponding EOI model may be generated using an appropriate EOIdata model and the POI models corresponding to the linked POIs.

In an example embodiment, an EOI model generation engine 610 isconfigured to receive human behavior information/data from, fromexample, user behavior database 260. For example, the human behaviorinformation/data may be used to determine and/or define one or morehuman behavior and/or interest criteria. In an example embodiment, thehuman behavior information/data may be used as an input for training anEOI model generation engine 610 using machine learning engine 650.

FIG. 8 provides a flowchart illustrating various processes andprocedures that may be performed to generate an EOI, according to anexample embodiment. Starting at block 702, the extraction engine 100receives data extraction information/data from external data extractionmodel 620. For example, the EOI model generation engine 610 (operatingon the network apparatus 10) may receive data extractioninformation/data. For example, the network apparatus 10 may comprisemeans, such as processor 12, memory 14, communications interface 16,and/or the like, for receiving and/or accessing data extractioninformation/data. In various embodiments, the data extraction model maydefine, identify, indicate, and/or the like at least a portion of theinformation/data that should be included in an EOI model. For example,the data extraction information/data may define, identify, indicate,and/or the like one or more fields, elements, and/or the like of atleast one EOI data model. In an example embodiment, the external dataextraction model 620 is a high cognitive load model 200 and/or acognitive navigation model 205 and the data extraction information/datamay indicate one or more data fields and/or elements to be included inat least one EOI data model such that the resulting EOI models may beused to efficiently and effectively identify high cognitive loadportions of a route based on the EOI model and/or efficiently andeffectively generate, extract, and/or determine familiarization contentfor a corresponding high cognitive load portion based on the EOI model.

At block 704, navigation information/data is received from thenavigation engine 300. In an example embodiment, route information/datais received from the navigation engine 300. In an example embodiment,route information/data is navigation information/data corresponding to aroute from an origin location to a destination location. For example,the EOI model generation engine 610 (operating on the network apparatus10) may receive navigation information/data (e.g., provided by thenavigation engine 300). In an example embodiment, the navigationinformation/data comprises static elements of POI information/data;dynamic elements of POI information/data; expected, historical, current,and/or (near) real-time weather information/data; information/dataregarding road segments and/or intersections linking road segments(e.g., link and/or node data records); and/or other geographicinformation/data and/or information/data corresponding to at least aportion of a road network. For example, the network apparatus 10 maycomprise means, such as processor 12, memory 14, communicationsinterface 16, and/or the like, for receiving and/or accessing navigationinformation/data.

At block 706, the EOI generation engine 610 (operating on the networkapparatus 10) generates, defines, determines, and/or the like one ormore EOI data models. For example, the network apparatus 10 may comprisemeans, such as processor 12, memory 14, and/or the like, for generating,defining, determining, and/or the like one or more EOI data models. Invarious embodiments, the EOI data models are generated, defined,determined, and/or the like based on the navigation information/data andthe data extraction information/data. In various embodiments, the EOIdata models may be generated, defined, determined, and/or the like usingmachine learning. For example, the EOI model generation engine 610, viathe machine learning engine 650, may learn patterns that may be used toidentify clusters and/or groups of POIs that may be linked (e.g., viastatic and/or dynamic elements of the POIs) to generate an EOI. Invarious embodiments, a cluster and/or group of POIs that may be linkedto generate an EOI are related to one another in way that is likely toaffect the driving experience (e.g., the experienced cognitive load) ofa user navigating a route past at least one POI of the EOI. For example,the cluster and/or group of POIs may be linked in a manner that isexpected to cause increased pedestrian and/or vehicle traffic betweentwo or more POIs, increase the driving effort required to effectivelyand/or efficiently navigate past at least a portion of the EOI, and/orthe like. For example, a first POI of a first EOI may be a school, asecond POI of the first EOI may be an ice cream shop within a predefineddistance of the school, and a third POI of the first EOI may be a crosswalk between the school and the ice cream shop. In another example, afirst POI of a second EOI is a stadium, a second POI of the second EOIis a public parking lot within a predefined distance of stadium, and athird POI of the second EOI is a cross walk signal along a route betweenthe public parking lot and the stadium.

In various embodiments, the EOI model generation engine 610 generatesand/or defines EOI data models. For example, an EOI data model may be atemplate data record that may be populated with EOI information/data todescribe an EOI. In various embodiments, an EOI data model comprisesstatic elements and dynamic elements. In an example embodiment, the EOIdata model may define and/or indicate one or more relationshipconditions that a cluster and/or group of POIs must satisfy to be linkedas an EOI corresponding to the EOI data model. In an example embodiment,the relationship conditions comprise one or more predefined distancecriteria. For example, the EOI data model may indicate that each POI ofthe cluster and/or group of POIs that defines the EOI should be within apredefined distance of all of the other and/or at least one other POI ofthe cluster and/or group of POIs. The EOI data model may indicate and/ordefine the predefined distance. In an example embodiment, the one ormore relationship conditions may comprise one or more human behaviorand/or interest criteria. For example, the human behavior and/orinterest criteria may indicate types of POIs that may be related throughhuman behavior and/or interest. In an example embodiment, a humanbehavior and/or interest criteria may correspond to a road geometryand/or topology that may give rise to increased cognitive load when auser navigates a route along, by, and/or in the vicinity of the clusterand/or group of EOIs. Inn an example embodiment, a human behavior and/orinterest criteria may correspond to one or more reasons that mayincrease human and/or vehicle traffic between two or more POIs.

In an example embodiment, an EOI data model may correspond to aparticular type of EOI. For example, a first EOI data model may bedefined for use with EOIs that correspond to increased pedestriantraffic and a second, different EOI data model may be defined for usewith EOIs that correspond to difficult road topologies. For example, anEOI data model may define a predefined distance corresponding to thecorresponding type of EOIs. In an example embodiment, the POIs of an EOIare located within the predefined distance from one another. In anexample embodiment, each POI of an EOI is located within the predefineddistance from at least one other POI of the EOI. Thus, in variousembodiments, the POI linked to generate an EOI are geographically linked(e.g., by being located within the predefined distance of one another)in addition to being related via human behavior and/or interest.

At block 708, the EOI generation engine 110 (operating on the networkapparatus 10) may generate, identify, and/or determine one or more EOIs.For example, the network apparatus 10 may comprise means, such as theprocessor 12, memory 14, and/or the like, for generating, identifying,and/or determining one or more EOIs. In an example embodiment, the oneor more EOIs are generated, identified, and/or determined using the oneor more EOI data models and/or template EOI data records generated bythe EOI model generation engine 610.

In an example embodiment, the one or more EOIs are generated,identified, and/or determines based on navigation information/data(e.g., route information/data). For example, an EOI generation engine110 may analyze navigation information/data using and/or based on theEOI data models, template EOI data records, and/or the like to identifyand/or determine clusters and/or groups of POIs that meet therelationship conditions of an EOI data model and/or template EOI datarecord. When a cluster and/or group of POIs that meet the relationshipconditions of an EOI data model, the EOI generation engine 110 maygenerate an EOI model (e.g., populate and EOI data model and/or templateEOI data record) with EOI information/data generated, determined, and/orextracted from the POI models corresponding to the POIs of the clusterand/or group of POIs corresponding to the EOI. In various embodiments,the relationship conditions of an EOI data model and/or template EOIdata record comprise the human behavior and/or interest relationshipcriteria and the predefined distance criteria corresponding to the EOIdata model and/or template EOI data record. For example, the EOIgeneration engine 110 may analyze navigation information/data (e.g.,route information/data) to identify clusters and/or groups of POIs thatsatisfy the relationship conditions of one or more EOI models, and, forclusters and/or groups of POIs identified as satisfying the relationshipconditions, generate corresponding EOI models describing the identifiedand/or generated EOI comprising the cluster and/or group of POIs.

In an example embodiment, a plurality of EOI generation engines 110 maybe used. For example, each EOI generation engine 110 may be configuredto identify EOIs corresponding to a particular EOI data model and/ortemplate EOI data record. In another example, each EOI generation engine110 may be configured to identify EOIs of a particular type.

At block 710, the identified, generated, and/or determined EOIs may beprovided. For example, the EOI generation engine 110 (operating on thenetwork apparatus 10) may provide EOI models (and/or portions thereof)describing the identified, generated, and/or determined EOIs. Forexample, the EOI models (and/or portions thereof) may be received by theidentification engine 130 (operating on the network apparatus 10) foruse in identifying and/or determining high cognitive load portions of aroute and/or by the content generating engine 120 (operating on thenetwork apparatus 10) for use in generating, extracting, and/ordetermining familiarization information/data (e.g., familiarizationcontent) for one or more high cognitive load portions of a route. Forexample, the network apparatus 10 may comprise means, such as processor12, memory 14, communications interface 16, and/or the like forproviding and/or receiving the one or more EOI models and/or portionsthereof.

At block 712, the identified, generated, and/or determined EOIs may bestored, for example, in an EOI data store (e.g., an EOI database). Forexample, the network apparatus may cause EOI models describing theidentified, generated, and/or determined EOIs to be stored in an EOIdata store. For example, the network apparatus 10 may comprise means,such as processor 12, memory 14, communications interface 16 and/or thelike, for storing EOI models describing the identified, generated,and/or determined EOIs in an EOI data store. For example, theidentification engine 130 (operating on the network apparatus 10) and/orthe content generating engine 120 (operating on the network apparatus10) may access EOI models and/or portions thereof stored in the EOI datastore for use in identifying and/or determining high cognitive loadportions of a route and/or generating, extracting, and/or determiningfamiliarization information/data (e.g., familiarization content) for oneor more high cognitive load portions of a route. In various embodiments,the EOI models corresponding to the identified, generated, and/ordetermined EOIs are stored for use in performing one or more navigationfunctions (e.g., localization, route determination, lane level routedetermination, lane maintenance, route guidance, lane level routeguidance, provision of traffic information/data, provision of lane leveltraffic information/data, provision of route familiarization content,and/or the like).

In an example embodiment, the data extraction information/data receivedfrom the external data extraction model 620 may comprise one or more EOIdata models, template EOI data records, and/or the like. In such anembodiment, the extraction engine 100 may receive the data extractioninformation/data as described with relation to block 702, receive thenavigation information/data as described with relation to block 704, andthen move to identifying, generating, and/or determining EOIs asdescribed with relation to block 708. For example, in some embodiments,the data extraction information/data may comprise one or more EOI datamodels, template EOI data records, and/or the like, and the EOIgeneration system 600 may not comprise and/or may not make use of theEOI model generation engine 610.

In various embodiments, the familiarizationinformation/data comprises familiarization content to be provided to auser (e.g., via an IUI provided via the user interface 28 of the vehicleapparatus 20) and information/data regarding how and when/where thefamiliarization content is to be provided to the user. In an exampleembodiment, the high cognitive load model 200 is and/or comprises acognitive navigation model 205 configured for modeling human cognitiveprocessing in various navigation scenarios. In an example embodiment,the cognitive navigation model is trained using navigationinformation/data, user behavior information/data, and/or feedbackdirectly from one or more users (e.g., a user questionnaire). In anexample embodiment, the cognitive navigation model is trained usingmachine learning with support from a machine learning engine.

In various embodiments, a high cognitive load model 200 may bepersonalized for an individual user, a class of users, and/or may begeneric to all users. For example, a high cognitive load model 200 thatis generic to all users may be used as the data extraction model 620 ofan EOI generation system 600 and high cognitive load models 200 that arepersonalized for a user and/or a class of users may be used as the highcognitive load model 200 of familiarization system 500, in an exampleembodiment. In various embodiments, personalizing the high cognitiveload model for an individual user may include the using user behaviorinformation/data (e.g., stored in the user behavior database 260),information/data from a driver questionnaire completed by the user,profile information/data from a user profile corresponding to the user,user preferences (e.g., as indicated in the user profile correspondingto the user), and/or other information/data corresponding to theindividual user in the generation of the high cognitive load model 200.In various embodiments, users may be grouped into classes of users. Invarious embodiments, users are grouped into classes based on one or moreuser attributes that users have in common. For example, users may begrouped based on one or more of age, driving experience, number of yearsdriving, memory problems, individual user preferences, similar answersbeing provided by the users on a driver questionnaire, drivingaggressiveness, and/or the like. In various embodiments, personalizingthe high cognitive load model for a class of users may include the usinguser behavior information/data (e.g., stored in the user behaviordatabase 260) corresponding to one or more users in the class of users,information/data from driver questionnaires completed by one or moreusers in the class of users, profile information/data from user profilescorresponding to one or more users in the class of users, userpreferences (e.g., as indicated in user profiles corresponding to one ormore users in the class of users), and/or other information/datacorresponding to one or more users in the class of users in thegeneration of the high cognitive load model 200.

FIG. 9 provides a block diagram of an example model generation system900. In an example embodiment, the model generation system 900 comprisessome form of direct user input, such as a driver questionnaire 915. Inan example embodiment, the driver questionnaire 915 takes the form of asurvey or other questionnaire that a user may complete and the answersprovided by the user may be stored in a questionnaire database and/orthe like. In an example embodiment, the driver questionnaire 915 maytake the form of information/data extracted from a user profilecorresponding to a user and/or user preferences. For example, the driverquestionnaire 915 may provide the dynamic model creation engine 910 withdemographic information/data regarding a individual user and/or class ofusers (e.g., age, number of years driving, driving experience level,and/or the like). In an example embodiment, the driver questionnaire 915may provide the dynamic model creation engine 910 with information/dataregarding scenarios that a user may find stressful to navigate (e.g., anavigation scenario that raises the user's cognitive load). For example,in one example embodiment, the driver questionnaire 915 may ask users torate various scenarios on a scale of not stressful to very stressful,and/or the like. In various embodiments, the results and/or responses todriver questionnaires 915 submitted by one or more users may be storedin a questionnaire data store (e.g., database) on memory 14 of thenetwork apparatus 10 and/or another memory accessible to the networkapparatus 10.

In various embodiments, the model generation system 900 comprises userbehavior database 260. In various embodiments, the user behaviordatabase is stored in memory 14 of the network apparatus 10 and/or inanother memory accessible to the network apparatus 10. For example, thedynamic model creation engine 910 may be personalized for an individualuser and/or class of users based on user behavior information/datastored in the user behavior database 260, a user profile, and/or thelike. For example, the dynamic model creation engine 910 may analyzeuser behavior information/data stored in the user behavior database 260to determine how users in general, users of a class of users, and/or anindividual user has responded to various navigation scenarios in thepast. For example, the determination of types of navigation scenariosthat are stressful (e.g., increase cognitive load for a user navigatingthrough the navigation scenario) may be based on behaviorinformation/data stored in the user behavior database 260.

In various embodiments, the model generation system 900 comprises amodel configuration engine 450. In an example embodiment, the modelconfiguration engine 450 is part of the configuration engine 400. Invarious embodiments, the model configuration engine 450 operates on thenetwork apparatus 10 and/or as a distributed application operating inpart on the network apparatus 10 and in part on the vehicle apparatus20. In various embodiments, the model configuration engine 450 isconfigured to receive configuration information/data, store and/orformat the received configuration information/data and provide theconfiguration information/data to the dynamic model creation engine 910.For example, one or more users may fill out an operator/driverquestionnaire or survey regarding navigation scenarios and/or drivingsituations that may cause the user stress (e.g., increase the user'scognitive load), user preferences and/or feedback regarding what type offamiliarization content (e.g., content, how the content is provided,and/or the like) help to reduce the user's cognitive load, and/or thelike. The questionnaire or survey results may be provided to the modelconfiguration engine 450 as configuration information/data. For example,in an example embodiment, the model configuration engine 450 may accessdriver questionnaire results and/or responses stored in a questionnairedata store and provide the results and/or responses to the dynamic modelcreation engine 910.

In an example embodiment, the model generation system 900 comprises anavigation engine 300. In an example embodiment, a navigation engine 300is configured for providing navigation information/data. For example, anavigation engine 300 may access a geographic database and provide thedynamic model creation engine 910 with geographic information/data suchas POI information/data (static and/or dynamic elements), EOIinformation/data (static and/or dynamic elements), roadwayinformation/data (e.g., link and/or node data records), and/or the like.In an example embodiment, the navigation engine 300 may operate at leastin part on the network apparatus 10 to provide the dynamic modelcreation engine 910 with geographic information/data.

In various embodiments, the dynamic model creation engine 910 isconfigured to generate a high cognitive load model 200. In variousembodiments, the dynamic model creation engine 910 generates a cognitivenavigation model 205. For example, the cognitive navigation model 205may be generated based on the user behavior information/data,questionnaire information/data, and navigation information/data. In anexample embodiment, the cognitive navigation model 205 is trained usingthe user behavior information/data, questionnaire information/data,and/or navigation information/data via machine learning supported by themachine learning engine 950. In an example embodiment, the machinelearning engine 950 may use an unsupervised machine learning algorithmto train the cognitive navigation model 205. For example, the dynamicmodel creation engine 910 may be a neural network and/or deep net thatis configured and/or trained to receive user behavior information/data,questionnaire information/data, and/or navigation information/data asinput and provide one or more instances of scenario information/dataand/or scenario templates corresponding to high load navigationscenarios (e.g., navigation scenarios that are likely and/or expected toincrease a user's cognitive load as the user navigates the navigationscenario) as output.

In various embodiments, the cognitive navigation model 205 is comprisesone or more instances of scenario information/data and/or scenariotemplates that each correspond to a high load navigation scenario. Invarious embodiments, a high load navigation scenario may relate to anEOI and/or POI (e.g., based on static and/or dynamic elements thereof),road geometry and/or topology, a maneuver to be navigated through (e.g.,taking a right and then taking an immediate left on a road havingmultiple lanes of traffic in the same direction), and/or the like. Invarious embodiments, an instance of scenario information/data and/or ascenario template may be compared to route information/data (e.g., bythe identification engine 130) to identify high cognitive load portionsof a route corresponding to and/or matching a high load navigationscenario described by the instance of scenario information/data and/orscenario template. For example, an instance of scenario information/dataand/or scenario template may comprise the information/data required foridentifying a portion of a route (based on the route information/data)that is similar to an example high load navigation scenario by matchinga navigation scenario profile corresponding to the example high loadnavigation scenario, and/or that satisfies one or more thresholdrequirements determined and/or defined based on an example high loadnavigation scenario and provided by the instance of scenarioinformation/data and/or scenario template.

In various embodiments, an instance of scenario information/data and/orscenario template comprises information/data identifying, indicating,and/or the like familiarization content to be generated, determined,and/or extracted for a high cognitive load portion that matches,satisfies, and/or is identified based on the instance of scenarioinformation/data and/or scenario template. For example, the instance ofscenario information/data and/or scenario template may indicate textand/or graphics to be provided to a user (e.g., via the user interface28) and/or a text and/or graphic template(s) to be populated andprovided to the user (e.g., via the user interface 28) when the userreaches the trigger point corresponding to high cognitive load portion.In an example embodiment, the instance of scenario information/dataand/or scenario template comprises information/data that defines thetrigger point, a type of trigger point (e.g., distance to the highcognitive load portion and/or time before the user is expected to reachthe high load), and/or other information/data that may be taken intoaccount when determining the trigger point for high cognitive loadportions matching the navigation scenario.

As noted above, a dynamic model creation engine 910 may be personalizedfor an individual user, a class of users, and/or users in general.Similarly, the cognitive navigation model 205 may be personalized for anindividual user, class of users, and/or users in general. In an exampleembodiment, the cognitive navigation model 205 is personalized by beinggenerated and/or created by a dynamic model creation engine 910 that ispersonalized for the same individual user, class of users, and/or usersin general. In an example embodiment, a dynamic model creation engine910 that is not personalized for users in general (e.g., that is notparticular to an individual user and/or class of users) may be used togenerate a cognitive navigation model 205 that is personalized for anindividual user and/or class of users by considering user behaviorinformation/data and/or questionnaire information/data corresponding tothe individual user and/or class of users when generating the cognitivenavigation model 205. In an example embodiment, a dynamic model creationengine 910 that is personalized to a class of users may be used togenerate a cognitive navigation model 205 that is personalized to anindividual user that is a member of the corresponding class of users byconsidering user behavior information/data and/or questionnaireinformation/data particular to the individual user when generating thecognitive navigation model 205.

In various embodiments, the cognitive navigation model 205 may comprisean indicator of the individual user and/or class of users the cognitivenavigation model 205 is personalized for. For example, the cognitivenavigation model 205 may comprise a user identifier corresponding to auser profile corresponding to the individual user to which the cognitivenavigation model has been personalized. For example, the cognitivenavigation model 205 may comprise a class identifier corresponding to aclass of users for which the cognitive navigation model has beenpersonalized. In an example embodiment, if the cognitive navigationmodel 205 is personalized for users in general, the cognitive navigationmodel 205 may or may not comprise an indication that the cognitivenavigation model 205 corresponds to a generic user and/or users ingeneral.

FIG. 10 provides a flowchart illustrating example processes, procedures,and/or operations for generating and providing a cognitive navigationmodel 205 for use in determining and providing a user withfamiliarization content as a user navigates a route. Starting at block1002, a dynamic model creation engine 910 is generated, programmed,trained, and/or the like. For example, the network apparatus 10 maygenerate and/or trained a dynamic model creation engine 910. Forexample, the network apparatus 10 may comprise means, such as processor12, memory 14, and/or the like, for generating and/or training a dynamicmodel creation engine 910. For example, the network apparatus 10 may usea machine learning engine 950 (e.g., operating on the network apparatus10) to train the dynamic model creation engine 910. In variousembodiments, user behavior information/data may be accessed and/orreceived from the user behavior database 260, questionnaireinformation/data corresponding to driver questionnaire 915 may beaccessed and/or received from the questionnaire database, and/ornavigation information/data may be accessed and/or received fromnavigation engine 300 and used to generate, program, and/or train thecognitive navigation model 205.

At block 1004, a cognitive navigation model 205 is generated. Forexample, the network apparatus 10 may operate a dynamic model creationengine 910 to generate a cognitive navigation model 205. For example,the network apparatus 10 may comprise means, such as processor 12,memory 14, and/or the like for generating a cognitive navigation model205. In an example embodiment, the generation of the cognitivenavigation model 205 comprises identifying and/or determining high loadnavigation scenarios (e.g., navigation scenarios that are likely and/orexpected to be stressful and/or cause the user increased cognitive loadas the user prepares to and/or navigates the navigation scenario) (atblock 1006) and generating scenario information/data and/or scenariotemplates corresponding to the identified and/or determined navigationscenarios that are likely and/or expected to be stressful for a usernavigating the navigation scenario (at block 1008).

For example, the dynamic model creation engine 910 may be operated, atblock 1006, to analyze navigation information/data (e.g., based on userbehavior information/data and/or questionnaire information/data) toidentify and/or determine high load navigation scenarios.

Once one or more high load navigation scenarios have been identifiedand/or determined, the dynamic model creation engine 910 may generatecorresponding instances of scenario information/data and/or scenariotemplates, at block 1008. In various embodiments, an instance ofscenario information/data and/or scenario template comprises scenarioidentifying information/data for identifying high cognitive loadportions of a route by identifying portions of a route that match and/orare similar to a high load navigation scenario and information/data forgenerating familiarization information/data (e.g., familiarizationcontent and/or a trigger point) for an identified high cognitive loadportion that matches and/or is similar to the high load navigationscenario.

For example, an instance of scenario information/data and/or scenariotemplate may comprise scenario identifying information/data foridentifying and/or determining portions of a route, based on routeinformation/data (e.g., EOI information/data, POI information/data,roadway information/data (e.g., link and/or node records), and/or thelike corresponding to a route), that match the high load navigationscenario. In an example embodiment, a portion of a route matches a highload navigation scenario if the portion of the route matches a profileof the high load navigation scenario (e.g., as provided by thecorresponding instance of scenario information/data and/or scenariotemplate). In an example embodiment, a portion of a route matches a highload navigation scenario if the portion of the route satisfies one ormore threshold requirements corresponding to the high load navigationscenario (e.g., as provided by the corresponding instance of scenarioinformation/data and/or scenario template). In an example embodiment, aportion of a route matches a high load navigation scenario if theportion of the route fits a template provided by the correspondinginstance of scenario information/data and/or scenario template. Thus, invarious embodiments, an instance of scenario information/data and/orscenario template comprises a profile of a navigation scenario, one ormore threshold requirements corresponding to a high load navigationscenario, a template corresponding to a high load navigation scenario,and/or the like. In various embodiments, the profile of a high loadnavigation scenario, one or more threshold requirements corresponding toa high load navigation scenario, template corresponding to a high loadnavigation scenario, and/or the like is generated by the dynamic modelcreation engine 910 responsive to identifying a high load navigationscenario.

For example, an instance of scenario information/data and/or scenariotemplate may comprise familiarization content and/or a template that maybe populated and provided as familiarization content for an identifiedhigh cognitive load portion that matches and/or is similar to thecorresponding high load navigation scenario. For example, an instance ofscenario information/data and/or scenario template may comprise textand/or graphics to be provided to a user (e.g., via the user interface28) and/or text and/or graphic template(s) to be populated and providedto the user (e.g., via the user interface 28) when the user reaches thetrigger point corresponding to an identified high cognitive load portionthat matches and/or is similar to the corresponding high load navigationscenario. In various embodiments, the instance of scenarioinformation/data and/or scenario template may comprise information/dataindicating how the familiarization content should be provided to a userin various situations. For example, in an example embodiment, theinstance of scenario information/data and/or scenario template comprisesinformation/data that defines the trigger point, a type of trigger point(e.g., distance to the high cognitive load portion and/or time beforethe user is expected to reach the high load), and/or otherinformation/data that may be taken into account when determining thetrigger point for high cognitive load portions matching the high loadnavigation scenario. For example, the instance of scenarioinformation/data and/or scenario template may indicate that if the useris traveling at greater than a particular speed, the familiarizationcontent is to be provided with greater urgency and/or more assertively(e.g., louder, in a more assertive voice/tone, and/or the like).

At block 1010 the cognitive navigation model 205 is provided. Forexample, the cognitive navigation model 205 may be provided to anextraction engine 100 (operating on the network apparatus 10). Forexample, the network apparatus 10 may comprise means, such as processor12, memory 14, and/or the like, for providing the cognitive navigationmodel 205. In various embodiments, an extraction engine 100 may use thecognitive navigation model 205 to generate familiarizationinformation/data for a route. For example, the extraction engine 100 mayuse the cognitive navigation model 205 to identify and/or determine highcognitive load portions of a route and to generate, determine, and/orextract familiarization information/data for the high cognitive loadportions.

At block 1012, user feedback is received. For example, the networkapparatus 10 may receive user feedback from one or more vehicleapparatuses 20. For example, the network apparatus 10 may comprisemeans, such as processor 12, memory 14, and/or communications interface16, for receiving feedback from one or more vehicle apparatuses 20. Inan example embodiment, the user feedback is provided via user responsesto a follow up driver questionnaire (e.g., completed via an IUI providedvia the user interface 28). In an example embodiment, the user feedbackis provided as biometric data corresponding to the user that wascaptured as the user navigated the route. In an example embodiment, thebiometric data is captured by one or more sensors of the vehicleapparatus 20. In an example embodiment, the biometric data is capturedby a user apparatus such as a wearable device (e.g., smart watch,Fitbit, and/or the like) that provides the captured biometric data tothe vehicle apparatus 20 and/or to the network apparatus 10 (e.g., viathe cloud and/or one or more networks 50). In an example embodiment, theuser feedback is provided via analyzing user behavior information/datacaptured as the user navigated the route. For example, one or moresensors of the vehicle apparatus 20 may capture information/data as theuser navigates the route that indicate and/or correspond to userbehavior (e.g., speed, acceleration, intensity of braking, use ofblinkers, and/or the like). The user behavior information/data may beprovided to the network apparatus 10 for analysis and/or inclusion inthe user behavior database 260. In various embodiments, user feedbackmay be associated with a individual user, a class of users, and/or withusers in general. As should be understood, various forms of userfeedback may be received by the network apparatus 10.

At block 1014, the dynamic model creation engine 910 is updated based onthe received user feedback. For example, the network apparatus 10 mayanalyze the received user feedback and update the dynamic model creationengine 910 based thereon. For example, the network apparatus 10 mayprovide the received user feedback to the dynamic model creation engine910 as user behavior information/data and/or questionnaireinformation/data and update, continue to configure and/or train (e.g.,using machine learning engine 950), and/or re-configure and/or retrain(e.g., using machine learning engine 950) the dynamic model creationengine 910 based at least in part on the received user feedback. Forexample, the network apparatus 10 may comprise means, such as processor12, memory 14, and/or the like, for updating, continuing to configureand/or train, and/or re-configuring and/or retraining the dynamic modelcreation engine 910 based at least in part on the received userfeedback. The process may then return to block 1004.

In addition to embodying the network apparatus 10 and/or vehicleapparatus 20 of an example embodiment, a navigation system may alsoinclude or have access to a geographic database that includes a varietyof data (e.g., map information/data) utilized in constructing a route ornavigation path, determining the time to traverse the route ornavigation path, matching a geolocation (e.g., a GNSS determinedlocation) to a point on a map, a lane of a lane network, and/or link,one or more localization features and a corresponding location of eachlocalization feature, and/or the like. For example, a geographicdatabase may include road segment or link data records, point ofinterest (POI) data records, entity of interest (EOI) data records,localization feature data records, and other data records. More, feweror different data records can be provided. In one embodiment, the otherdata records include cartographic (“carto”) data records, routing data,and maneuver data. One or more portions, components, areas, layers,features, text, and/or symbols of the POI or event data can be storedin, linked to, and/or associated with one or more of these data records.For example, one or more portions of the POI, event data, or recordedroute information can be matched with respective map or geographicrecords via position or GNSS data associations (such as using known orfuture map matching or geo-coding techniques), for example. In anexample embodiment, the data records may comprise nodes, connectioninformation/data, intersection data records, link data records, POI datarecords, EOI data records, and/or other data records. In an exampleembodiment, the network apparatus 10 may be configured to modify,update, and/or the like one or more data records of the geographicdatabase. For example, the network apparatus 10 may modify, update,generate, and/or the like map information/data corresponding to links,road segments, nodes, intersection, POIs, EOIs, and/or the like and/orthe corresponding data records, a localization layer (e.g., comprisinglocalization features) and/or the corresponding data records, and/or thelike.

In an example embodiment, the road segment data records are links orsegments, e.g., maneuvers of a maneuver graph, representing roads,streets, or paths, as can be used in the calculated route or recordedroute information for determination of one or more personalized routes.The intersection data records are end points corresponding to therespective links or segments of the road segment data records. The roadlink data records and the intersection data records represent a roadnetwork, such as used by vehicles, cars, and/or other entities.Alternatively, the geographic database can contain path segment andintersection data records or nodes and connection information/data orother data that represent pedestrian paths or areas in addition to orinstead of the vehicle road record data, for example.

The road/link segments, intersections, and/or nodes can be associatedwith attributes, such as geographic coordinates, street names, addressranges, speed limits, turn restrictions at intersections, and othernavigation related attributes, as well as EOIs and/or POIs, such asgasoline stations, hotels, restaurants, museums, stadiums, offices,automobile dealerships, auto repair shops, buildings, stores, parks,etc. The geographic database can include information/data about the EOIsand/or POIs and their respective locations in the EOI and/or POI datarecords. The geographic database can also include data about places,such as cities, towns, or other communities, and other geographicfeatures, such as bodies of water, mountain ranges, etc. Such place orfeature data can be part of the EOI and/or POI information/data or canbe associated with EOIs and/or POIs or EOI and/or POI data records (suchas a data point used for displaying or representing a position of acity). In addition, the geographic database can include and/or beassociated with event data (e.g., traffic incidents, constructions,scheduled events, unscheduled events, etc.) associated with the POI datarecords, EOI data records, or other records of the geographic database.

The geographic database can be maintained by the content provider (e.g.,a map developer) in association with the services platform. By way ofexample, the map developer can collect geographic data to generate andenhance the geographic database. There can be different ways used by themap developer to collect data. These ways can include obtaining datafrom other sources, such as municipalities or respective geographicauthorities. In addition, the map developer can employ field personnelto travel by vehicle along roads throughout the geographic region toobserve features and/or record information about them, for example.Also, remote sensing, such as aerial or satellite photography, can beused. In an example embodiment, the geographic database may be generatedand/or updated based on map information/data generated and/or extractedfrom sensor information/data provided by vehicle apparatuses 20 throughthe use of update and/or notification messages. In various embodiments,the vehicle apparatuses 20 may be onboard vehicles owned and/or operatedby and/or on behalf of members of the general public or onboard vehiclesowned and/or operated as part of a private fleet.

The geographic database can be a master geographic database stored in aformat that facilitates updating, maintenance, and development. Forexample, the master geographic database or data in the master geographicdatabase can be in an Oracle spatial format or other spatial format,such as for development or production purposes. The Oracle spatialformat or development/production database can be compiled into adelivery format, such as a geographic data files (GDF) format. The datain the production and/or delivery formats can be compiled or furthercompiled to form geographic database products or databases, which can beused in end user navigation devices or systems.

For example, geographic data is compiled (such as into a platformspecification format (PSF) format) to organize and/or configure the datafor performing navigation-related functions and/or services, such asroute calculation, route guidance, map display, speed calculation,distance and travel time functions, and other functions. Thenavigation-related functions can correspond to vehicle navigation orother types of navigation. The compilation to produce the end userdatabases can be performed by a party or entity separate from the mapdeveloper. For example, a customer of the map developer, such as anavigation device developer or other end user device developer, canperform compilation on a received geographic database in a deliveryformat to produce one or more compiled navigation databases. Regardlessof the manner in which the databases are compiled and maintained, anavigation system that embodies a network apparatus 10 and/or vehicleapparatus 20 in accordance with an example embodiment may determine thetime to traverse a route that includes one or more turns at respectiveintersections more accurately.
